APPARATUS FOR SEALING PRESERVING-JARS.

Application filed July 24,

To all whom it may concern Be it known that I, ARTHUR EGGL'ETON\Vonsrnn, a subject of the King of Great Britain, and a resident of thecity of Vancouver, in the Province of British Columbia, Canada, haveinvented certain new and useful Improvements in Apparatus for SealingPreserving-Jars, of which the following is a specification.

My invention relates to improvements in apparatus for sealing preservingjars, such as those containing fruit, meat, milk or any perishablearticle and the object of my invention is to provide an apparatus by theuse of which such are, after filling, may be exhausted of air and thensealed tightly, which apparatus is simple in construction and operationand capable of being manufactured and sold at a low cost.

I attain this object by the construction illustrated in the accompanyingdrawing in which the figure shows a front view of the device, with theside removed.

The apparatus consists of a box 1 divided into upper and lowercompartments 2 and 3, one side of the lower compartment being providedwith a door (not shown) capable of being opened and closed in the usualmanner, this compartment being air tight when the door is closed. On onewall in the inside of the box is a hook 4: on which are hung a number ofspring clips 5 of dif ferent sizes and each of which is adapted to bedetachably mounted horizontally of the box by inserting it in a clipmember 6 secured to the compartment wall so as to grip a jar or bottleplaced in it, as shown, the bottle then resting on the bottom of thecompartment, as in the case of a milk bottle, or on supporting blocks 7and 8 which are used for bottles or jars of less height, the thicknessof the blocks provided varying according to the height of the jars to besupported, being, however, such as will support the jar so that its capwill be in. close proximity to the nozzle hereinafter described.

In the compartment 3 is rotatably mounted a crank shaft 9 the operationof which by a handle 10 or any other suitable means operates air suctionpumps 11 and 12 the suction pipes 13 and 141 of which are conSpecification of Letters Patent.

nected to a transverse pipe 15 which forms a branch of a vertical pipe16 the lower end of which extends into the compartment 2 as a nozzle 17directly above the center of the jar cover 18 while its opposite endextends upwardly through the top of compartment 3 and is provided with asuitable valve 19 by the operation of which the pipe 16 may be opened orclosed to or from the atmosphere. Air holes or vents 20 are formed in awall of the compartment 3 to permit escape of the air drawn thereintofrom the lower compartment by the pumps 11 and 12.

The manner in which the apparatus is operated and its utility will bereadily seen and may be described briefly as follows The bottle or jarcontaining the articles to be preserved is placed in the lowercompartment 2 with the cap on being rested on the bottom of thecompartment, or on the blocks 7 and 8, as may be required, and the dooris then closed. The pumps are then set in operation, the valve-19 beingfirst of all closed, whereupon all the air in compartment 2 and in thejar will be drawn out into com mrtment 3, creating a vacuum incompartment 2. The valve 19 is then opened so that the air rushes intothe pipe 16 and out through the nozzle into compartment 2, striking thebottle cap in the center and driving it down into place so that thebottle becomes tightly and perfectly sealed. 1

From the foregoing it will be seen that I have devised a practical andeffective apparatus for sealing jars in a simple and convenient manner.

What I claim as my invention is An apparatus for sealing preserving jarscomprising an air tight compartment adapted to inclose a jar and itscap, a vertical air duct having its lower end extending into saidcompartment and its outer end closed by a valve, said air duct beingprovided intermediate its ends with a lateral extension and pumpingmechanism for creating a vacuum in said extension to exhaust the airwithin the compartment.

Dated at Vancouver, B. (1., this 25th day of June, 1919.
